Preston Roller Pulla Bush
If you already have existing kits that you'd like to convert to a Pulla system, this Preston Innovations Roller Pulla Bush could just be the answer.
When fitted to a reinforced area of the pole it allows you to place the bush accurately to suit how you fish. It features an unique side entry PTFE bush system with an integrated PTFE roller for ultra-smooth flow of elastic through your top kit when playing fish.
Preston recommend that you seek professional fitting that is available from many tackle shops or pole repairers.
